Answer to Problem 50A
Explanation of Solution
Alkanes are compounds containing carbon and hydrogen atoms having single bond(s) between carbon atom(s) in the structure. For number of carbons atoms in alkane chain, the prefix is given as:
Carbon-1 meth
Carbon-2 eth
Carbon-3 prop
Carbon-4 but
Carbon-5 pent
Carbon-6 hex
Carbon-7 hept
Carbon-8 oct
Carbon-9 non
Carbon-10 dec
The given name is ethane that means the parent chain has 2 number of carbons in the chain and there is no substituent in the chain. So, the structural formula of ethane is:
Interpretation:
The structural formula of hexane needs to be drawn.
Concept introduction:
The hydrocarbon compounds that contains single bond(s) between carbon atom(s) are said to be saturated hydrocarbon. Hydrocarbon compounds containing single bonds only are said to be alkane.

Answer to Problem 50A
Explanation of Solution
The given name is hexane that means the parent chain has 6 number of carbons in the chain and there is no substituent in the chain. So, thestructural formula of hexane is:
Interpretation:
The structural formula of propane needs to be drawn.
Concept introduction:
The hydrocarbon compounds that contains single bond(s) between carbon atom(s) are said to be saturated hydrocarbon. Hydrocarbon compounds containing single bonds only are said to be alkane.

Answer to Problem 50A
Explanation of Solution
The given name is propane that means the parent chain has 3 number of carbons in the chain and there is no substituent in the chain. So, the structural formula of propane is:
Interpretation:
The structural formula of heptane needs to be drawn.
Concept introduction:
The hydrocarbon compounds that contains single bond(s) between carbon atom(s) are said to be saturated hydrocarbon. Hydrocarbon compounds containing single bonds only are said to be alkane.

Answer to Problem 50A
Explanation of Solution
The given name is heptane that means the parent chain has 7 number of carbons in the chain and there is no substituent in the chain. So, the structural formula of heptane is:
