SATHEE: Chemical Bonding And Molecular Structure Question 485

Chemical Bonding And Molecular Structure Question 485

Question: Which of following statement is true-

Options:

A) Absolutely pure water does not contain any ions

B) London forces is directly proportional to more number of loosely held electron

C) Allene is polar due to its non-planar structure

D) $C H_{3} O C H_{3}$ is less volatile than $C_{2} H_{5} O H$ due to higher molecular weight.

Show Answer

Answer:

Correct Answer: B

Solution:

(1) $H_{2} O \to H^{+} + O H^{-}$ $K_{w} = 10^{- 14}$ at $25^{o}$ Even in conductivity water $(H_{2} O)$ is found to be dissociated into $H^{+}$ and $O H^{-}$ . (2) More the number of loosely held electron, greater will be their tendency for being polarized deformed i.e., the magnitude of formal charge increases, hence London forces increases. (3) $H_{2} C = C = C H_{2}$ (Non planar) $μ_{D} = 0$ (4) In $C H_{3} C O C H_{3}$ there is no H-bonding hence more volatile, while in $C_{2} H_{5} O H$ intermolecular H-bonding is present hence less volatile, due to association.
