CxH(2x-2) + HCl ⇒ CxH(2x-1)Cl
M M + 36,5
M + 36,5 = 167,59/100·M
0,6759 M = 36,5 M = 54 g/mol 14x - 2 = 54 14x = 56 x = 4 C4H6
daca A = ciclobutena ⇒ B = cloro-ciclobutan
daca A = metil-ciclopropena ⇒ B + cloro,metil-ciclopropan (2izomeri)
2. C6H5-C3H7 + nCl2 ⇒ C6H5-C3H(7-n)Cln + nHCl
M = 120+ 34,5n
35,5n·100 /(120+ 34,5n) = 47,65 77n = 120+34,5n 42,52n = 120 n≈3
ptr, n = 3 C6H5-C3H4Cl3 10650/223,5 = 47,65% (D)
3. R(OH)x + xCH3-CO-O-CO-CH3 ⇒ R( -OCO-CH3)x + xCH3-COOH
n anhidrida = 102 /102 = 1mol alcool : CnH(2n+2)Ox
n anhidrida = x· n alcool 1 = x·31/ (14n+ 2+16x) 16x + 14n+2 = 31x
15x = 14n +2 ptr. n = 2 x = 2 alcool = etan-diol
