Q. Huckel's rule states that the hydroxyl group which is attached directly to a double-bonded carbon atom becomes an aldehyde or a ketone.

In dehydrohalogenation reactions the preferred product is that alkene which has the greatest number of alkyl groups attached to the doubly bonded carbon atoms. This rule is known as:

Q. The alpha carbon in an organic compound refers to the carbon atom directly attached to the functional group, such as a carbonyl group.

Q. Geometrical isomerism is a kind of stereoisomerism which is present in the compounds containing a double bond

(C = C, C = N . N = N)

and arise due to the restricted or frozen rotation about the double bond. The atoms or groups attached to the doubly bonded carbons must be different. In aldoximes, the isomer is named as syn if hydrogen and hydroxyl groups are on the same side of

C = N

bond and if these are on opposite sides, the isomer is named as anti. In ketoximes, the prefixes syn and anti indicate which group of ketoxime is syn or anti to hydroxyl group.
