Please people I need an answer a, b,c, d,e. Name the following alkanes? Please!

a. 2 - Methylpropane

b. 2 - Methylbutane

c. 4 - Ethylheptane

d. 3 - Ethyl - 4 - Methylheptane

e. 3 - Ethyl - 3 - Methylheptane

Explanation:

a. 2 - Methylpropane - As the structure has 3 carbon atoms and one methyl group at second carbon.

b. 2 - Methylbutane: Numbering for longest carbon chain has 4 carbon atoms and methyl group attached at second carbon atom.

c. 4 - Ethylheptane: Numbering from right to left or left to right, longest chain has 7 carbon atoms (heptane) and two carbon atoms (ethyl) attached at fourth carbon atom.

d. 3 - Ethyl - 4 - Methylheptane: Numbering from right to left, longest chain has 7 carbon atoms (heptane), two carbon atoms (ethyl) attached at forth carbon atom and one methyl group attached at fourth carbon atom.

e. 3 - Ethyl - 5 - Methylheptane: numbering from left to right, longest chain has 7 carbon atoms (heptane), two carbon atoms (ethyl) attached at third carbon atom and one methyl group attached at fifth carbon atom.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
