2-Methylpropanal, also known as isobutyraldehyde, is a branched-chain aldehyde with the molecular formula C4H8O. Its structural formula depicts a central carbon atom double-bonded to an oxygen atom and single-bonded to two methyl groups and a hydrogen atom. Understanding the molecular geometry of 2-methylpropanal is crucial for predicting its physical and chemical properties.
2-Methylpropanal
-methylpropanal, also known as isobutyraldehyde, is an organic compound with the formula (CH3)2CHCHO. It is a colorless liquid with a pungent odor. It is a structural isomer of butanal.
Structural Formula
The structural formula of 2-methylpropanal is:“` O || CH3-C-CH2-CH3“`The molecule consists of a central carbon atom bonded to a methyl group (-CH3), a methylene group (-CH2-), and a carbonyl group (-CHO). The methyl group and the methylene group are both attached to the central carbon atom by single bonds, while the carbonyl group is attached by a double bond.
Molecular Geometry, Draw 2-methylpropanal. include all hydrogen atoms
The molecular geometry of 2-methylpropanal is trigonal planar around the central carbon atom. This is because the central carbon atom has three electron groups around it: the two methyl groups and the carbonyl group. The electron groups repel each other, causing the molecule to adopt a trigonal planar geometry.
