Which is most likely an example of an angular molecule? NH_(3) H_(2)O SiCl_(4) H_(2)CO

The most likely example of an angular molecule among the given options is (formaldehyde).Explanation:- (ammonia) has a trigonal pyramidal shape due to the presence of a lone pair of electrons on the nitrogen atom.- (water) has a bent or angular shape due to the presence of two lone pairs of electrons on the oxygen atom.- (silicon tetrachloride) has a tetrahedral shape with no lone pairs on the silicon atom.- (formaldehyde) has a trigonal planar shape with no lone pairs on the carbon atom.Therefore, the correct answer is .
