a. Draw three constitutional isomers with molecular formula C3H8O.
b. How many constitutional isomers can you draw for C4H10.O?
(a)
Interpretation:
The three constitutional isomers of molecular formula
Concept introduction:
Constitutional isomers are having the same molecular formula and different bond connectivity between the atoms.
The general formula for an alkane is
Equation for finding constitutional isomers for a molecule
Answer to Problem 1P
Explanation of Solution
The given molecular formula is
Therefore,
The two possible alcohols are,
The possible ether is,
(b)
Interpretation:
The numbers of constitutional isomers of molecular formula
Concept introduction:
Constitutional isomers are having the same molecular formula and different bond connectivity between the atoms.
Answer to Problem 1P
The numbers of constitutional isomers of molecular formula
Explanation of Solution
The given molecular formula is
Therefore,
There will be five alcohol isomers (due to four carbons) and two ether isomers.
Hence,
