7. Alcohol, phenol and ethers — Chemistry STD 12 Science — Question

$[A]$ $HClO_4$ is more acidic than $\mathrm{HClO}$ because of the resonance stabilization of its anion

$[B]$ $HClO_4$ is formed in the reaction between $Cl_2$ and $H_2 O$

$[C]$ The central atom in both $HClO_4$ and $HClO$ is $s p^3$ hybridized

$[D]$ The conjugate base of $HClO_4$ is weaker base than $H_2 O$

$(a)$   $NCl_3$ is formed when $Cl_2$ is present in excess.

$(b)$   $N_2$ is formed when $Cl_2$ is present in excess.

$(c)$   $N_2$ is formed when $NH_3$ is present in excess.

$(d)$   $NCl_3$ is formed when $NH_3$ is present in excess.

Correct option are

$C{H_2} = CH{(C{H_2})_8}COOH + HBr\xrightarrow{{{\text{peroxide}}}}$
