br3sih is _____ due to br _____.

not distorted, electronegativity
not distorted, lone pairs
distorted, lone pairs
distorted, ionization potential

Explanation:

In \(Br_3SiH\), the central \(Si\) atom has 4 bonding pairs (3 \(Si - Br\) and 1 \(Si - H\)). However, \(Br\) atoms have lone pairs. The presence of these lone pairs causes repulsion, which distorts the molecular geometry. Electron - negativity (\(Br\) is more electronegative than \(H\)) could also have an effect, but the main reason for distortion in terms of molecular geometry (VSEPR - like considerations) is the lone pairs on \(Br\). Ionization potential is not relevant to the molecular shape distortion here.

Answer:

distorted, lone pairs
