Answer:
Plausible structure has been given below
Explanation:
- Molar mass of
is 44 g/mol and molar mass of
is 18 g/mol
- Number of mole = (mass/molar mass)
4.04 g of =
= 0.0918 moles of
1 mol of contains 1 mol of C atom
So, 0.0918 moles of contains 0.0918 moles of C atom
1.24 g of =
= 0.0689 moles of
1 mol of contain 2 moles of H atom
So, 0.0689 moles of contain
of
or 0.138 moles of
Moles of C : moles of H = 0.0918 : 0.138 = 2 : 3
Empirical formula of hydrocarbon is
So, molecular formula of one of it's analog is
