Why is o-nitrophenol is more volatile than p-nitrophenol?
Why is o-nitrophenol is more volatile than p-nitrophenol?
O-Nitrophenol forms intramolecular H bond whereas molecules of P-Nitrophenol get associated through intermolecular H bond. During boiling, the strong intermolecular H bonding increases the boiling point but intramolecular H bonding cannot do so. Therefore, O-Nitrophenol is more steam volatile than P-Nitrophenol.
Which isomer is more volatile o-nitrophenol or p-nitrophenol?
o-nitrophenol
The structure of para-nitrophenol is: Hence, we can say that o-nitrophenol is more volatile than p-nitrophenol because of intermolecular hydrogen bonding in p-nitrophenol.
Which is more reactive o-nitrophenol or p-nitrophenol?
p- Nitrophenol is a stronger acid than o-nitrophenol.
Which of the following is more volatile a o-nitrophenol B M nitrophenol c/p-nitrophenol D O&P nitrophenol?
Solution : o-nitrophenol is more volatile because of intramolecular hydrogen bonding in it whereas p-nitrophenol is associated due to intermolecular hydrogen bonding.
Why the boiling point of o-nitrophenol is lower than that of p-nitrophenol?
P-nitrophenol shows intermolecular hydrogen bonding. So it has higher bonding point. Whereas o-nitrophenol shows intra molecular H-bonding hence lower boiling point.
Which isomer is the most volatile?
Which of the following isomers is more volatile: o-nitrophenol or p-nitrophenol? In o-nitro phenol, -OH is linked to –NO2 by means of intramolecular H-bonding so, it is highly volatile.
Which is more acidic ortho meta or para?
Ortho nitrophenol is less acidic than para nitrophenol because of the intermolecular hydrogen bonding which makes the loss of proton very difficult. So, para nitrophenol is more acidic.
What is the relationship between concentration and the intensity of absorbed photons?
The Beer-Lambert law states that the concentration of a chemical solution is directly proportional to its absorption of light. There is a linear relationship between the concentration and the absorbance of the solution, which enables the concentration of a solution to be calculated by measuring its absorbance.
Which of the following is most volatile 1 p-nitrophenol 2 m nitrophenol 3 o-nitrophenol 4 all of these?
o-nitro phenol is most volatile .
Which of the following compounds is more soluble in water o-nitrophenol or p-nitrophenol give reasons for your answer?
Due to intramolecular H-bonding, −OH group is not available to form a hydrogen bond with water. Hence o-nitrophenol is sparingly soluble in water while m- and p-nitrophenol are soluble due to intermolecular H-bonding with water.
Which of the following has greater melting point o-nitrophenol or p-nitrophenol explain with help of structures?
p-nitrophenol has higher melting point than o-nitrophenol because p-nitrophenol is more symmetrical than o-nitrophenol.
Which has higher boiling point ortho nitrophenol or para nitrophenol Why?
Solution : p-nitrophenol has higher boiling point because there is intermolecular H-bonding while in O-nitrophenol , there is intramolecular H-bonding .
Which one is more volatile?
CH3−OH is more volatile. Volatility is due to the tendency to evaporate. The tendency of volatility of CH3−OH is low. Dipole attraction and London force occurs in the molecules.
Which molecule is the most volatile?
The table below shows some substances arranged in order of decreasing boiling point and increasing volatility. In the table, boron is the least volatile and hydrogen the most volatile substance.
Which is more acidic among ortho meta or para?
Therefore correct acidic order of nitrophenols are para- > ortho- > meta-. Show activity on this post. In both ortho- and para-nitrophenol, there is one more resonance structure. So due to resonance effects both ortho- and para-nitrophenol are more acidic than the meta-nitrophenol.
Which is more acidic para meta or ortho?
Is para or ortho more stable?
Ortho form is more stable than para form at and above room temperature, whereas at low temperature para form is more stable.
Why is O-nitrophenol more steam volatile than p-nitro-phenol?
Verified by Toppr O-Nitrophenol forms intramolecular H bond whereas molecules of P-Nitrophenol get associated through intermolecular H bond. During boiling, the strong intermolecular H bonding increases the boiling point but intramolecular H bonding cannot do so. Therefore, O-Nitrophenol is more steam volatile than P- Nitrophenol.
Which is more volatile-O-nitrophenol or P-nitrobenzene?
Assertion: o-nitrophenol is more volatile than p-nitrophenol. Assertion: o-nitrophenol is more volatile than p-nitrophenol. Reason: Intramolecular hydrogen bonding is present in o-nitrophenol while intermolecular H – bonding is in p-nitrophenol. Please log in or register to add a comment.
What is the effect of intermolecular hydrogen bonding in nitrophenol?
Intermolecular hydrogen bonding leads to association of several molecules of p nitrophenol which results in high boiling point and less volatile nature. Video Explanation Solve any question of Alcohols Phenols and Etherswith:-
