Three acyclic alkenes (x,y,z) on catalytic hyrogenation give same alkane. On reaction with HCl (x,y,z) form same major tertiary halide product.Reductive ozonolysis of mixture of (x,y,z) gives a mixture of two moles of `CH_2=O` one moles of `CH_3CH=O` one mole of acetone, one mole of butanone and one mole of 2-methyl propanal, x,y and z do not have any stereoisomers.
What is true about x,y,z
A. These have molecules formula `C_3H_6`
B. x,y,z on catalytic hydrogenation give chiral alkanes
C. These are unbranced alkenes
D. These form same carbocation intermediate on reaction with HCl to give the major product.
