The molecular formula C 5 H 10 O 2 (molar mass: 102.13 g/mol) may refer to: tert-Butyl formate; Ethyl propionate; Hydroxypivaldehyde; Isobutyl formate; Isopropyl acetate; Methylbutanoic acids. 2-Methylbutanoic acid; 3-Methylbutanoic acid (isovaleric acid) Methyl butyrate; Methyl isobutyrate; Pivalic acid; Propyl acetate; Tetrahydrofurfuryl ...
Isobutyl formate (2-methylpropyl methanoate) is an organic ester with the chemical formula C 5 H 10 O 2. It is formed by the Fischer esterification of isobutanol with formic acid, with the aid of an acid catalyst. It is used as a flavor and fragrance ingredient because of its odor which is sweet, ethereal, and slightly fruity. [2] [3]

Ipso-substitution describes two substituents sharing the same ring position in an intermediate compound in an electrophilic aromatic substitution. Trimethylsilyl, tert-butyl, and isopropyl groups can form stable carbocations, hence are ipso directing groups. Meso-substitution refers to the substituents occupying a benzylic position.
Two methyl groups are the substituents attached to the central oxygen in diethyl ether. Because the two methyl groups are electropositive, greater s character will be observed and the real bond angle is larger than the ideal bond angle of 109.5 o. Methanol has one electropositive methyl substituent and one electronegative hydrogen substituent.

Depending on the substituents, olefins maintain varying degrees of allylic strain. In 3-methyl-1-butene, the interactions between the hydrogen and the two methyl groups in the allylic system cause a change in enthalpy equal to 2 kcal/mol. [7] [verification needed] As expected, with an increase in substituent size, the
The top 5 most common are the methyl, phenyl, chlorine, methoxy, and hydroxyl substituents. The total number of organic substituents in organic chemistry is estimated at 3.1 million, creating a total of 6.7×10 23 molecules. [11] An infinite number of substituents can be obtained simply by increasing carbon chain length.
