The boiling point of a molecule depend on strength of intermolecular interaction such as vanderwall interaction hydrogen bonding etc. Alkane such as $\mathrm{CH}_{3}-\left(\mathrm{CH}_{2}\right)_{3}-\mathrm{CH}_{3}$ being non polar have weakest force of attraction. Therefore, it is called London or dispersion force. Etheres such as $\mathrm{CH}_{3}-\mathrm{O}-\mathrm{CH}_{3}$ have small dipole moment thus very weak dipole-dipole interaction hence stronger than the London force. So it has lowest boiling point alcohol and acid are polar molecule so it has high boiling point.
4 $\mathrm{CH}_{2}=\mathrm{CH}-\mathrm{CH}_{2}-\ddot{\mathrm{NH}_{2}} \longleftrightarrow$ It does not show resonance because it does not have conjugated system
Explanation:
To show resonance system, molecule should be conjugated i.e. molecule must have alternate $\pi$-bond/ +ve charge/ -ve charge and lone pair must be present to show resonance effect. (d.) $\mathrm{CH}_{2}=\mathrm{CH}-\mathrm{CH}_{2}-\ddot{\mathrm{NH}_{2}} \longleftrightarrow$ It does not show resonance because it does not have conjugated system

Carbocation as an intermediate is likely to be formed in the reaction
Carbocation is formed when there is Hectrolytic bond cleavage Hexane on reaction with Anhydrous $\mathrm{AlCl}_{3}$ undergoes rearrangement and form $2^{\circ}$ carbocation which ultimately undergoes 2 methyl pentane.

In the Grignard reaction, which metal forms an organometallic bond?
1 Sodium
2 Titanium
3 Magnesium
4 Palladium
Explanation:
According to the Grignard reaction, magnesium metal forms an organometallic bond. The Grignard reaction is an organometallic chemical reaction in which alkyl, allyl, vinyl or aryl-magnesium halides is added to a carbonyl group. This can be prepared as $\mathrm{R}-\mathrm{X}+\mathrm{Mg} \stackrel{\text { ether }}{\longrightarrow} \mathrm{R}-\mathrm{Mg}-\mathrm{X}$
