Question

question 7

1. the bond angle in cl₂o is expected to be approximately

120°.
180°.
109.5°.
145°.
90°.

Explanation:

In Cl₂O, the central O atom has 2 bonding pairs (to Cl atoms) and 2 lone pairs. VSEPR theory predicts a tetrahedral electron domain geometry (4 electron domains). Lone pairs repel more strongly than bonding pairs, compressing the bond angle from the ideal tetrahedral 109.5°. The large Cl atoms also reduce repulsion between bonding pairs, leading to a bond angle slightly larger than the compressed angle in H₂O (~104.5°), matching the 110° option.

Answer:

110°
