: Tetraethyl lead is used as antiknocking agent. Antiknock agents are the compounds included in little amounts to engine power to improve the antiknocking ratings of fuel. Generally added to gasoline to raise its octane value. Tetraethyl Lead (TEL) is an organ metallic compound containing the harmful metal lead. TEL was once a major industrial compound of lead because of it is use as an antiknocking agent in gasoline.

What is $\mathrm{Z}$ in the following reaction? $\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CO}_2^{-} \mathrm{Na} \oplus \stackrel{\mathrm{NaOH} / \mathrm{CaO}}{\longrightarrow} \mathrm{Z}$
1 propane
2 $\mathrm{n}$ - butane
3 ethane
4 ethyne
Explanation:
: Sodium propanoate reacts with sodium hydroxide in presence of $\mathrm{CaO}$ to give the ethane.

The boiling points of four saturated hydrocarbons are given below. Which boiling point suggests maximum number of carbon atoms in its molecule:
1 $-162^{\circ} \mathrm{C}$
2 $-88.6^{\circ} \mathrm{C}$
3 $-0.5^{\circ} \mathrm{C}$
4 $-42.2^{\circ} \mathrm{C}$
Explanation:
: Boiling Point depends on the number of Carbon atom. Carbon atom is increase then the boiling point is also increase.

Phosgene is formed slowly from which one of the following on exposure to air and sunlight?
1 $\mathrm{CHCl}_3$
2 $\mathrm{H}_3 \mathrm{CCl}$
3 $\mathrm{H}_3 \mathrm{COH}$
4 $\mathrm{C}_2 \mathrm{H}_5 \mathrm{Cl}$
Explanation:
: In the presence of air and light, chloroform forms carbonyl chloride (also called phosgene) which is extremely poisonous. $\underset{\text { Clloroform }}{\mathrm{CHCl}_3}+\frac{1}{2} \mathrm{O}_2 \stackrel{\text { air wid light }}{\longrightarrow} \underset{\text { Phosgens }}{\mathrm{COCl}_2}+\mathrm{HCl}$
