An atom represented by X forms a compound with
1 answer:
Answer:
D) Mg .
Explanation:
Hello!
In this case, since compounds with the formula X3N2 suggest that the oxidation state of X is +2 because the oxidation state of nitrogen is -3 as it gains three electrons in order to attain a complete octet; among the given options, just magnesium (option D) Mg ) has such charge as it is in group 2A, which suggests it loses two electrons when forming ionic compounds:
Best regards!

Structure V reacts fastest with trimethylamine in SN2 reaction. Owing to less steric crowding in the transition state and ease of cleavage of the R - I bond
The question is incomplete, the complete question is shown in the image attache to this answer.
SN2 reaction is a type of nucleophilic reaction in which the nucleophile attacks the substrate from the reverse side. This is a synchronous reaction because the leaving group departs as the entering group attacks simultaneously in a hypervalent transition state.
SN2 reaction is favored by structure V owing to less steric crowding in the transition state and the easy of cleavage of the R - I bond. Hence, structure V reacts fastest with trimethylamine in SN2 reaction.
