Hydrocarbons Question 256

Question: Which of the following types of reaction occur when a reactant has got a double bond-

(i) Addition (ii) Photolysis (iii) Nucleophilic substitution (iv) Polymerization

Options:

A) (i) and (iv)

B) (i) and (ii)

C) (i), (ii) and (iv)

D) (i),(ii),(iii) and (iv)

Show Answer

Answer:

Correct Answer: A

Solution:

[a] Addition reaction occurs on a double bond.

The compound containing double bonds are also undergo polymerisation.

So, the correct option are both (i) and (iv) e.g.

$ CH_2=CH_2+HOCI\xrightarrow{{}}\underset{( additionreaction )}{\mathop{CH_2OH-CH_2Cl}} $

$ nCH_2=CH_2\xrightarrow{polymerisation}\underset{Polyethene}{\mathop{-{{[CH_2-CH_2-]} _{n}}}} $
