Which of the following does not show electromeric effect?
1 Alkenes
2 Ethers
3 Aldehydes
4 Ketones
Explanation:
Electromeric effect implies complete transfer of $\pi$-electrons in the presence of a reagent. Since, simple ethers do not contain any multiple bond. Hence, they do not show electromeric effect.

Which of the following compounds can be dehydrated very easily?
Decreasing order of dehydration of alcohols is $3^{\circ}>2^{\circ}>1^{\circ}$ because $3^{\circ}$ carbocation is more stable than $2^{\circ}$ carbocation which in turn is more stable than $1^{\circ}$ carbocation.

Which of the following is more electrophilic ?
1 Ethane
2 Ethylene
3 Acetylene
4 Methane
Explanation:
Electron deficient species are called electrophiles. Among the given, ethane and methane have complete octet and thus, do not behave like electrophile. Between ethylene $\left(\mathrm{CH}_{2}=\mathrm{CH}_{2}\right)$ and acetylene $(\mathrm{CH} \equiv \mathrm{CH})$, the later being more electron deficient, is better electrophile.
