Given below are two statements : In the light of the above statements, choose the correct answer from the options given below :

  1. Both Statement I and Statement II are true
  2. Both Statement I and Statement II are false
  3. Statement I is true but Statement II is false
  4. Statement I is false but Statement II is true

Answer

(1) Both Statement I and Statement II are true

Solution

Statement I: For the same halogen, the boiling point increases with the size of the alkyl group (larger surface area ⇒ stronger van der Waals forces): CH3CH2CH2I > CH3CH2I > CH3I ⇒ Statement I is true.

Statement II: As per NCERT, p-dichlorobenzene is more symmetric and fits more closely in the crystal lattice ⇒ higher melting point (p- 323 K; o- 256 K).

p-Dichlorobenzene is non-polar ( = 0) whereas o-dichlorobenzene is polar ⇒ weaker intermolecular forces in the p-isomer ⇒ lower boiling point (p- 448 K; o- 453 K) ⇒ Statement II is true.

Answer: (1)
