Homework Answers
Answer 1 : True
Explanation : While naming an alkane we have to select the longest chain regardless of any bends. There may be bends but we must look carefully and identify the longest chain.
Answer 2 : The IUPAC name of the given compound is 2-methyl-2-propanol.
Explanation : Here we have a 3 carbon parent chain so the word root is 'prop'. It has a hydroxy group and methyl group in the second position.
hence, the IUPAC name is 2-methyl-2-propanol.
Answer 3 : Name of two carbon saturated alkyl group is ethyl.
Explanation : The alkyl group is a alkane where a 'H' is missing. The rule of its nomenclature is quite simple first we need to find the parent chain and decide the word root and then use the suffix 'yl' after it.
For example : 6 member alkyl group will be called Hexyl group.

Give the IUPAC name for this alkane. 2,3-dimethyl-6-isopropylnonane Find the longest carbon chain in the molecule. Number the carbons in the main chain so that the substituents have the lowest possible numbers. Numbers are separated from other numbers by commas and numbers are separated from letters by hyphens. If there are more than one of any type of substituent, use the prefixes "di", "tri" etc. to indicate how many are present. Each must be given a number. Substituents should be...
