The following reaction,is an example of
1 \(\alpha \)-elimination
2 \(\beta \)-elimination
3 Hofmann elimination
4 None of this
Explanation:
When a haloalkane with \(\beta\)-hydrogen atom is heated with alc. \(\mathrm{KOH}\) solution, there is elimination of hydrogen atom from \(\beta \)-carbon and a halogen atom from \(\alpha \)-carbon atom( \(\beta\) - elimination).

In the reaction shown below the six membered ring is generated by shifting which bond?
1 1
2 2
3 3
4 4
Explanation:
Five membered ring is converted into six membered ring due to the shifting of first bond.

The conversion of 2-methylpropan-1-ol to 2-methylpropan-2-ol is
1 addition reaction
2 rearrangement reaction
3 substitution reaction
4 elimination reaction
Explanation:
The conversion of 2-methylpropan-1-ol to 2-methylpropan-2-ol is a rearrangement reaction. In these reactions, the carbon skeleton of a molecule is rearranged to give a structural isomer of the original molecule. Here, the alcohol group of 2-methylpropan-1-ol moves from one atom to another atom in the same molecule to give 2-methylpropan-2-ol.
