(A)An oxygen bonded to three hydrogens (an oxonium-type ion, H₃O⁺)Correct
(B)A neutral dimethyl ether, CH₃–O–CH₃, with two lone pairs on O
(C)A methoxide ion, CH₃–O⁻, with three lone pairs on O
(D)Neutral water, H–O–H, with two lone pairs on O

Answer: (A)

Solution

Oxygen normally forms two bonds (and carries two lone pairs) when neutral. An oxygen bonded to three atoms (as
