Prin hidrogenarea totala a compusului de condensare crotonica a doua molecule de 3-metil-butanal se obtine:
A.2,4-dimetil-butanol-1;
B.5-metil-2-izopropil-hexanol-1
C.2,5-dimetil-hexanol-1
D.3-metil-heptanol-1
E.5-metil-heptanol-1


Răspuns :

CH3-CH2-CH(CH3)-CH(=OH) + CH3-CH2-CH(CH3)-CH(=OH)-------condensare alcoolica-----> CH3-CH2-CH(CH3)-CH(OH)-CH2-CH2-CH(CH3)-CH(=OH) ---------crotonizare------> CH3-CH2-CH(CH3)-CH=CH-CH-CH(CH3)-CH(=OH)--- (-H2O) ====> CH3-CH2-CH(CH3)-CH2-CH2-CH2-CH(CH3)-CH2(OH)
