Which of the following statements is/are correct for these two reactions?

318170 How many sp hybridized C-atoms is are present in reactant ' A '?
\({\text{A}}\xrightarrow[{{\text{Pd - C/quinoline}}}]{{{{\text{H}}_{\text{2}}}}}{{\text{C}}_{\text{3}}}{{\text{H}}_{\text{6}}}\)

318171 The product that results when one mole of 1-pentyne is first treated with one mole of \(\mathrm{HCl}\) and then with one mole of \(\mathrm{H}-\mathrm{Br}\) is

318172 Assertion :
Addition of \(\mathrm{H}_{2} \mathrm{O}\) to acetylene occurs in presence of dil. \(\mathrm{H}_{2} \mathrm{SO}_{4}\) and \(\mathrm{HgSO}_{4}\) to give acetaldehyde.
Reason :
The reaction proceeds through electrophilic addition mechanism.

318173 But-2-yne is reacted separately with one mole of hydrogen as shown below:
\({\text{B}}\xleftarrow[{{\text{liq}}\,\,{\text{N}}{{\text{H}}_{\text{3}}}}]{{{\text{Na}}}}{\text{C}}{{\text{H}}_{\text{3}}} - {\text{C}}\mathop \equiv \limits_{ + {{\text{H}}_2}} {\text{C}} - {\text{C}}{{\text{H}}_{\text{3}}}\xrightarrow[\Delta ]{{{\text{Pd}}/{\text{C}}}}{\text{A}}\)
1. A is more soluble than B .
2. The boiling point and melting point of \({\text{A}}\) are higher and lower than B respectively.
3. A is more polar than B because dipole moment of A is zero.
4. \(\mathrm{Br}_{2}\) adds easily to B than A .
