N2Cl+CuCl
Elemental analysis shows presence of only carbon and hydrogen in the given
organic compound A. The compound A reacts with ozone to give additioin
product which on hydrolysis in presence of zinc dust gives a mixture of
methanal and ethanal.
i. Suggest the structure of A with necessary chemical reaction. [2]
ii. Name the product obtained by adding HBr with A and it’s IUPAC
name. [2]
iii. What happens when compound A under goes catalytic reduction [1]
Metal A has a heat capacity of 0.450 J/goC while metal B has a heat capacity of 1.250 J/go C. If both metals are supplied with 1000.0 J of energy, which one will heat up more? Explain by describing what specific heat capacity defines (i.e. more than “this number is bigger/smaller”)
