Abstract:
In the title compound, C17H18N4O5·0.47CH3OH, the virtually planar (r.m.s. deviation = 0.128 Å) carbonohydrazide mol-ecule is located on a twofold axis and conformation of its C=N bonds is E. There are short intra-molecular O-H⋯N hydrogen bonds between the hy-droxy groups and hydrazide N atoms. In the crystal, bifurcated N-H⋯(O,O) hydrogen bonds assemble the carbonohydrazide mol-ecules into a three-dimensional network. There are C 2 symmetric voids in this network, 47% of which are occupied by disordered methanol mol-ecules.

Aldehydes and Ketones with Water: Hydrate Formation
The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...
Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
