Question

Statement 1 : $HF$ forms two series of salts but $HCl$ not.
Statement 2 : $F$-atom is more electronegative than $Cl$- atom.

• A. If both Statement $1$ and Statement $2$ are true and the statement $2$ is the correct explanation of the statement $1$
• B. If both Statement $1$ and Statement $2$ are true but statement $2$ is not the correct explanation of the statement $1$
• C. If Statement $1$ is true but Statement $2$ is false
• D. If Statement $1$ is false but Statement $2$ is true

Answer 1

Answer: (B)

$HF$ forms $NaHF_2$ and $NaF$ salt due to its dimerised formula $H_2F_2$ on account of $H$-bonding. No doubt $F$ is more electronegative than $Cl$.
