Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Assertion

Lithium sulphate does not form alums.

Reason

$L i^{+}$ is too small to form a stable lattice required for double-salt/alum formation.

Assertion – The non-fusible impurities present in iron ore are removed by $C a C O_{3}$ .

Reason: $C a C O_{3}$ which decomposes into $C a O$ and $C O_{2}$ . The $C a O$ formed reacts with $S i O_{2}$ to remove silica

ASSERTION: n-Pentane and n-Hexane belong to a homologous series.

REASON: n-Pentane and n-Hexane belong to the same class of hydrocarbons and they differ by a - $C H_{2}$ - group.
