Question

3. Calculate the degrees of unsaturation for each of the following. Based on that provide 2 plausible structures for each. a) CyH14 b) CHEN 4. Fill in the products for the following. Make sure you consider stereochemistry for each. HBr KOIBu HOIBU HO H₂SO4 H₂O, a) BH3THF b) H2O2, NaOH, H2O a) NaH b) Br

Answer 1

3 Answer is

we know that unsaturation - a 2C+2+N-H-X 2 Degree of where c = number of c atoms N = Number of Natoms H = Number of H atoms X = number of halogen atoms Gotha &c=7, H=14 @ substitute the values then, of unsaturation - 2(7)+ato-14-0 Degree of unsaturation = 1 = 1 means it contains one ring(er) one double bond.

ç Ha N C = 7, H=9, N= 1 217) +2+1-9-0 Then Degree of unsaturation = un saturation: 217)+2+1-9-0 = 8 = 4 Degree of unsaturation 4 i-e.i) 1 ring (or) in a ringst a double bonds. + 3 double bonds ir (ar) 4 double bonds (vii) a double bonds 41 Triple bond (iv) (68) 1 double bond + 3 rings (0) (or) 1 triple bond (a double bonds) + 2 rings.
