Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R :

Assertion (A) :

\mathrm{BeCl}_{2}

and

\mathrm{MgCl}_{2}

produce characteristic flame

Reason (R) : The excitation energy is high in

\mathrm{BeCl}_{2}

and

\mathrm{MgCl}_{2}

In the light of the above statements, choose the correct answer from the options given below :

A $\mathrm{(A)}$ is true but $(\mathrm{R})$ is false
B Both (A) and $(\mathrm{R})$ are true and $(\mathrm{R})$ is the correct explanation of $(A)$
C (A) is false but (R) is true
D Both (A) and (R) are true but (R) is NOT the correct explanation of (A)

Accepted Answer

BeCl₂ and MgCl₂ do not produce characteristic flame because excitation energy is high in BeCl₂ and MgCl₂. Hence, the correct answer is option (C).
