Question

What is the molecular weight of Alkane with n = 2 , n=3 and n=4 ?​

Answer 1

• n = 2

C2H6

Mol. wt. = 12 × 2 + 1 × 6 = 30 g/mol

• n=3

C3H8

Mol. wt. = 12 × 3 + 1 × 8 = 44 g/mol

• n = 4

C4H10

Mol. wt. = 12 × 4 + 1 × 10 = 58 g/mol

Answer 2

Answer:

Explanation:

alkanes exist as a homologous series, in which adjacent ... does for the dietary fats and oils: the molecule has no carbon-to-carbon double ... alkanes—methane (CH4), ethane (C2H6), and propane (C3H8) and ... The principle of homology allows us to write a general formula for alkanes: CnH2n + 2.

an alkane, or paraffin is an acyclic saturated hydrocarbon. In ... This isomer is sometimes called the n-isomer (n for "normal", although it is not ... (2 isomers), dimethylpentane (4 isomers), 3-ethylpentane, 2,2,3- ... because changing the number of rings changes the molecular formula.
