Question

Плотность углеводорода по водороду равна 36 . Сколько изомеров можно написать для этого углеводорода ?

Answer 1

Это пентан, у него 3 изомера: н-пентан, 2-метилбутан и 2,2-диметилпропан

Answer 2

Calculating the number of possible isomers

The density of the hydrocarbon is given as 36 g/mol. This means the molecular formula is C3H8, as propane has a molar mass of 44 g/mol.

There is one possible structural isomer for C3H8: propane. Propane can exist in three structural isomers depending on the branching of the carbon chain: n-propane (no branches), isopropyl (one methyl group branch), and neopropyl (one ethyl group branch).

Therefore, the number of possible isomers for this hydrocarbon with a density of 36 g/mol is three.
