Amines Class 12 Chemistry Notes

Amines are derivatives of ammonia in which one or more hydrogen atoms have been replaced by alkyl, cycloalkyl, allyl or aryl groups. Amines are classified as 1º, 2º and 3º amines according to the number of hydrogen atoms replaced by the alkyl groups. Thus, the general formula of primary, secondary and tertiary amines may be written as RNH₂ , R₂NH, and R₃N, respectively. Nitrogen atom in Amines is sp³-hybridized so it has a tetrahedral structure.

Find molecular weight of A

Solution:

The product (A) biphenyl have the molecular formula C₁₂H₁₀
So, its moleculare weight is (12 × 12) + 10 = 154
