Vedclass · Answer

(B) To determine the $H-C-H$ bond angle, we look at the hybridization and geometry of the central carbon atom in each molecule:$I$ (Cyclopropylidene): The central carbon atom is $sp^2$ hybridized. Due to the ring strain in the three-membered ring, the $H-C-H$ bond angle is approximately $115^{\circ}$.$II$ (Ethene): The carbon atom is $sp^2$ hybridized. In a standard alkene, the $H-C-H$ bond angle is approximately $120^{\circ}$.$III$ (Methane): The carbon atom is $sp^3$ hybridized with a tetrahedral geometry. The $H-C-H$ bond angle is $109^{\circ} 28^{\prime}$ (or $\approx 109.5^{\circ}$).Comparing these values: $120^{\circ} (II) > 115^{\circ} (I) > 109.5^{\circ} (III)$.Therefore, the correct decreasing order is $II > I > III$.

$A. NO_3^-$	$1. sp^3$
$B. NH_2^-$	$2. sp$
$C. SCN^-$	$3. sp^3d$
$D. ICl_2^-$	$4. sp^2$

The correct order of decreasing $H-C-H$ bond angle in the following molecules is:
