Which of the following molecules has two lone pairs of electrons in the valence shell of its central atom?

The $H-C-H$ bond angle in $CH_4$ is $109.5^{\circ}$. Due to lone pair repulsion,the $H-O-H$ angle in $H_2O$ will:

Which of the following is not correctly matched?
Bond angle | Number of bond angles

The $I_3^-$ ion possesses:

The number of bond pairs,lone pairs present on the central atom of $SF_4$ molecule and its shape respectively are

The $H-N-H$ angle in ammonia is $107.6^{\circ}$ while the $H-P-H$ angle in phosphine is $93.5^{\circ}.$ Relative to phosphine, the $p$-character of the lone-pair on ammonia is expected to be
