Consider the following reactions sequence [figure] When the product (P) is subjected to Carius analysis using AgNO3, 1.0 g of the product (P) will produce g of the precipitate of AgBr. (Nearest Integer) (Given : molar mass in g mol-1 C : 12, H : 1, O : 16, N : 14, Br : 80, Ag : 108)

A student performed analysis of an aliphatic organic compound 'X' which on analysis gave C = 61.01%, H = 15.25%, N = 23.74%. This compound, on treatment with HNO2/H2O, produced another compound 'Y' which did not contain any nitrogen atom. However, the compound 'Y' upon controlled oxidation produced another compound 'Z' that responded to iodoform test. The structure of 'X' is :

1. CH3-CH2CH(NH2)-CH3
2. CH3CH2CH2NH2
3. Ph-CH(CH3)-NH2
