26
what words are considered in ALPHABETICAL ORDER
ISO AND NEO ARE CONSIDERED WHILE SEC AND TERT ARE NOT CONSIDERED di tri and tetra are not considerd
27
bis ,tris, tetrakiss words are used when
when two complex compounds are connected to a single carbon atom
28
order of priority(first 5)

48
when is ring given priority during nomenclature
if the no of c in connecting chain is less than or equal to no of c in ring
49
when is chain given priority during nomenclature
if the no of c in connecting chain is greater than no of c in ring
50
other name of methanol

53
in bicyclo compounds the numbering goes along
largest bridge
54
the number of carbons in bicyclo compounds are in?
decreasing order
55
write structure of 2-methyl bicyclo(2,2,2)octane

56
numbering is independent of
functional group
57

small ring
58
structure of 5-methyl spiro(2,4)heptane
SEE STRUCTURES
59
if there is a cho and oh in a cyclo compound then
then oh acts as a substituent and is given same peiority as methyl
60
HOW TO NUMBER ALICYCLIC COMPOUNDS
THE SUBSTITIUENT WHICH COMES FIRST IN THE ALPHABETICAL ORDER IS GIVEN THE LOWEST NUMBER AND IS ALSO ACCORDING TO LOWEST SUM RULE
61
IF SIDE CHAIN CONTAINS FUNCTIONAL GROUP OR A MULTIPLE BOND THEN
ALICYCLIC RING BECOMES SUBSTITUENT IRRESPECTIVE OF SIZE OF THE RING
62
IF MORE THAN 1 ALICYCLIC RING IS ATTACHED TO A SINGLE CHAIN
IT IS NAMED AS CYCLOALKYL ALKANE
63
IF DOUBLE OR TRIPLE BOND ARE PRESENT IN THE RING THEN
NUMBERING IS DONE SUCH THAT MULTIPLE BOND GETSB LOWEST NUMBER
64
EXPLAIN THE NAMING OF 1,6DIMETHYL CYCLOHEX1-ENE
COZ PRIORITY IS GIVEN TO THE CARBON IN THE DOUBLE BOND WHICH IS ATTACHED TO METHYL GROUP
65
IF RING CONTAINS MULTIPLE BOND AND SIDE CHAIN CONTAINS FUNCTIONAL GROUP
THEN RING IS SUBSTITUENT
66
IF RING AND CHAIN BOTH HAVE FUNCTIONAL GROUPS
IF SIDE CHAIN HAS HIGHER PRIORIT FUNCTIONAL GROUP THEN THE RING BECOMES THE SUBSTITUENT VICE VERSA
67
IF RING AND CHAIN BOTH HAVE SAME FUNCTIONAL GROUPS
IF THE NUMBER OF CARBONS IN RING IS EQUAL OR GREATER THAN THAT OF SIDE CHAIN THEN RING BECOMES Parent chain
68
if ring is connected to benzene
benzene is parent chain
69
if an alicyclic ring is directly connected to carbon containing functional group
then the c atom of functional group is not included in parent chain and the special type of naming is used
