Consider the substitution reaction of H2S-BH3 with NH3, which generates two product molecules (ignore the states of matter), assuming that no species exceeds the octet rule. Given the following information: Step 1: There are two products in the first step; one product, which is an intermediate, has a trigonal planar molecular geometry. Step 2: The intermediate from Step 1 reacts in Step 2 to form a compound with two sp3 hybridized atoms. Overall: One bond is formed and one bond is broken. One of the products has a bent molecular geometry and smells like rotten eggs.
