b. How will you prove that C4H8 and C5h10 are identical?


A carbon compound ‘A’ having melting point 156K and boiling point 351K has molecular formula C. with2h6O is soluble in water in all proportions.

A. Identify ‘A’ and draw its electron point structure.

b. Write the molecular formulas of any two homologs of ‘A’.

10. Two pea plants – one with round yellow seeds (RRYY) and the other with wrinkled green (Rryy) seeds, produce F1 offspring that have round, yellow (RrYy) seeds.

When F1 plants are self pollinated, what new combination of characters is expected in F2 progeny? When a total of 160 seeds are produced in the F2 generation, how many seeds will be produced with the combination of these new characters? Explain with reason.
