JEE Mains · Chemistry · STD 11 -p-Block elements - I
A group \(13\) element \('X'\) reacts with chlorine gas to produce a compound \(XCl_3. XCl_3\) is electron deficient and easily reacts with \(NH_3\) to form \(Cl_3X \leftarrow NH_3\) adduct, however, \(XCl_3\) does not dimerize. \(X\) is
- A \(B\)
- B \(Al\)
- C \(In\)
- D \(Ga\)
Answer & Solution
Correct Answer
(A) \(B\)
Step-by-step Solution
Detailed explanation
\(BCl_3\) \(B+C{{l}_{2}}\to \underset{\begin{smallmatrix} [does\,not\,dimerise\,due\,to\, \\ (p\pi -p\pi )back\,bonding] \end{smallmatrix}}{\mathop{BC{{l}_{3}}}}\,\xrightarrow{N{{H}_{3}}}\) \(BCl_3\) is electron deficient but it does not form dimer like \(Al,Ga\) or \(In\)…
