Birch reduction of toluene leads to a product with molecular formula C_(7)H_(10) . On ozonolysis followed by reduction with Dimethyl sulphide 2 product are obtained X & Y.Number of active methylene hydrogens present in X=a and in Y=b . Then find a+b

A compound 'X' on ozonolysis followed by reduction gives an aldehyde, C_(2)H_(4)O and 2-butanone. Compound 'X' is:

Compound X with molecular formula C_(6)H_(10)O form a semicarbazone and give negative Tollen's and lodoform tests. Upon reduction

A compound X with moleuclar formula C_(3)H_(8)O can be oxidized to a compoud Y with the molecular formula C_(3)H_(6)O_(2) . X is most likely to be a:

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
