What are the structural isomers for c10h22?

Answer 1

- Cyclobutane: four carbons single-bonded in a square pattern, each with two hydrogens.

H2C----CH2

| |

H2C----CH2

- 1-butene: four carbons in a chain with a double bond between the first and second carbons:

H2C==CH--CH2--CH3

- 2-butene: four carbons in a chain with a double bond between the second and third carbons:

H3C--CH==CH--CH3

Answer 2

There are 75 isomers of decane (C10H20)

Some other examples which are also difficult to count:

1. hexane C6H14 = CH3(CH2)4CH3 has 5 isomers
2. heptane C7H16 = CH3(CH2)5CH3 has 9 isomers
3. octane C8H18 = CH3(CH2)6CH3 has 18 isomers
4. nonane C9H20 = CH3(CH2)7CH3 has 35 isomers
5. decane C10H22 = CH3(CH2)8CH3 has 75 isomers

Answer 3

there are exactly 75 isomers of decane
