Solution

The correct option is D Assertion is incorrect but Reason are correct
Tert-Butyl bromide $({M e}_{3} C - B r)$ and sodium ethoxide $(N a O E t)$ will react to form alkene.
${M e}_{3} C - B r + N a - O - C_{2} H_{5} \to {M e}_{2} C = C H_{2} + C_{2} H_{5} O H + N a B r$
Thus, assertion is incorrect but reason is correct.

Q. Assertion: The impurities such as

{SiO}_{2}

present in iron ore is removed by

{CaCO}_{3}

.

Reason:

CaO

formed by decomposition of

{CaCO}_{3}

reacts with

{SiO}_{2}

to form slag.

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
