Visual representation for Chemistry

A

$CH_3OH$

B

$C_2H_5OH$

C

HO- $CH_2$ - $CH_2$ -OH

D

OH

Answer

HO- $CH_2$ - $CH_2$ -OH

Explanation

Solution

Ethylene glycol, with the formula $\mathrm{HO-CH_2-CH_2-OH}$ , is widely used as an antifreeze agent because it lowers the freezing point of the liquid in the radiator.

The compound used for antifreeze is ethylene glycol $\mathrm{HO-CH_2-CH_2-OH}$ since it depresses the freezing point.
