Some basic rules for the nomenclature of substituted cycloalkanes are as follows - 1. Parent Chain- Always use the cycloalkane as the parent chain. 2. Numbering the Cycloalkane- When numbering the carbons of a cycloalkane, start with a substituted carbon so that the substituted carbons have the lowest numbers. When two or more different substituents are present, number according to alphabetical order. 3. Halogen Substituents- Halogen substituents are treated exactly like alkyl groups The IUPAC name of the given compounds are as follows - (a) vinylcyclobutane (b) ( E ) - 1 -(hex- 3 -en- 1 -yl)cyclohex- 1 -ene (c) 3 -ethyl- 6 -methylcyclohex- 1 -ene (d) ethylidenecyclohexane

Write the IUPAC names of the following compounds. ( a ) ( b ) ( c ) ( d ) ( e ) ( f ) ( g ) ( h )

Rules for naming aliphatic compounds having polyfunctional groups. A compound is said to be polyfunctional compound if it contains more than one functional group. The multiple bond is also considered as a functional group. In IUPAC system, one of the functional groups is chosen as the principal functional group (secondary suffix). The remaining functional groups (secondary functional groups) are treated as substituents and indicated by prefixes. The first step in the naming of poly functional compounds is the selection of principal functional group. It gives the class name of the structure. The second step is the selection of Parent chain. The parent chain is so selected that it includes the maximum number of functional groups including the principal group. The third step is the numbering parent chain. The parent chain is numbered from the side of principal functional group i.e., it gets lowest number. If a molecule contains both carbon-carbon double or triple bonds, the two are treated at par in seeking the lowest number combination. However, if the sum of numbers turns out to be the same starting from either of the carbon chain; then lowest number is given to the carbon-carbon double bond. Such compounds are named as alkenynes (a derivative of alkynes rather than alkenes) with numbering as low as possible given to the multiple bonds In case two substituents of same seniority occupy identical positions in relation to the end of the chain, the lowest number should be given to the Substituent in alphabetical order. Substituents, side chains and secondary functional groups are named in alphabetical order. (a) 3 -Chlorobutan- 2 -ol (b) 2 -Methylbut- 3 -en- 1 -ol (c) 5 -(Aminomethyl)- 3 -ethylheptan- 2 -ol (d) 3 -Butylpentane- 2 , 4 -dione (e) 5 -Oxoheptane- 3 -sulfonic acid (f) 3 -( 2 -Bromoethyl)hexan- 2 -ol (g) 2 -Chloro- 4 -ethoxy- 3 -methoxy- 5 -methylhexane (h) 2 -Cromo- 1 -chloro- 3 -methylbutane- 1 -sulfonic acid
