,b) : Octane number of petrol can be increased by adding some small amount of certain chemicals known as anti-knock agent or compound. e.g - TEL or $\mathrm{Et}_4 \mathrm{~Pb}$. In the modern days some special types of antiknock agents are used to increase the octane number of petrol by increasing the number of carbons in the chain known as methyltert-butyl ether $\mathrm{CH}_3 \mathrm{OC}\left(\mathrm{CH}_3\right)_3$. Hence, the option A and B are correct.

Which of the following compounds would have the highest boiling point?
: $\mathrm{CH}_3 \mathrm{OH}$ (methanol) has highest boiling point because there is a intermolecular hydrogen bonding in methanol and high electronegative of $\mathrm{O}$-atom, is strong. Therefore, $\mathrm{CH}_3 \mathrm{OH}$ has the highest boiling point.

Mustard gas is a
1 Oil gas
2 Poisonous gas
3 Fuel gas
4 Life gas
Explanation:
: Sulfur mustard is more commonly as mustard gas. This name was first used when the chemical was sprayed durning the attacks of world war-I. It yellow colour of mustard and may take on when mixed with other chemicals mustard gas are extremely poisonous gas and have powerful blistering effects on victims.
