The compound having the molecular formula C_(3)H_(9)N can represent

An optically active compound A (assume dextrorotatory) has the molecular formula C_(7)H_(11)Br . A reacts with hydrogen bromide, in the absence of peroxides to yield isomeric products, B and C, with the molecular formula C_(7)H_(12)Br_(2) . Compound B is optically active, C is not. Treating B with 1 mol of potassium butoxide yields (+)-A . Treating C with 1 mol of potassium tert-butoxide yields (+-)-A . Treating A with potassium tert-butoxide yields D(C_(7)H_(10)) . Subjecting 1 mol of D to ozonolysis followed by treatement with zinc and acetic acid yields 2 moles of formaldehyde and 1 mole of 1,3-cyclopentanedione. The optically active compound 'A' is
