=>
100% ........................................ 5,08% H
14n+62 ..................................... 2n-2 g H
=> n = 514,96/128,88 = 4
=> acidul este butandioic
monoesterul al acidului butandioic cu un alcool saturat monohidrolic ciclic

100% .................................... (5,08+2,45)% H
116+14x ................................ 4+2x
=> x = 473,48/94,58 = 5
=> alcoolul este ciclopentanol
