Because the straight-chain isomers have stronger interaction with one another compared to branched-chain isomers.

Because the straight-chain isomers have weaker interaction with one another compared to branched-chain isomers.

The lower interaction between branched-chain isomers will result in less energy required to break it apart.

The bonded atoms in alkanes are at an angle of 109.5°to each other.

If one of the hydrogen atoms of methane is replaced with a carbon atom bonded to three hydrogen atoms, the next hydrocarbon, propane, is formed.

Alkanes contain only single covalent bonds, they are saturated hydrocarbons.

Methane and ethane belong to the family of hydrocarbons called alkanes.

If two or more chains have the same number of carbon atoms, the chain with the greater number of branching points becomes the parent.

of carbon atoms present in the molecule.

The name of alkanes ends with a suffix 'ene”. A hyphen separates the number and the substituent.

The parent chain is determined based on the longest continuous chain
