Question

carbon 1
linear bent tetrahedral trigonal planar trigonal pyramidal
carbon 1
carbon 2
carbon 3

Explanation:

Step1: Analyze Carbon 1

Carbon 1 is bonded to 4 atoms (4 H atoms, but in the structure, it's bonded to 3 H and connected to Carbon 2, wait no—wait, Carbon 1: looking at the structure, Carbon 1 has 4 single bonds (3 H and 1 C - Carbon 2). So the electron - domain geometry for a carbon with 4 single bonds is tetrahedral. So for Carbon 1, the geometry is Tetrahedral.

Step2: Analyze Carbon 2

Carbon 2 is double - bonded to O and single - bonded to Carbon 1 and Carbon 3. The double bond counts as one domain, and the two single bonds. So total electron domains: 3 (double bond to O, single bond to C1, single bond to C3). The geometry for 3 electron domains is trigonal planar. So Carbon 2 has Trigonal Planar geometry.

Step3: Analyze Carbon 3

Carbon 3 is bonded to 4 atoms (3 H and 1 C - Carbon 2). So similar to Carbon 1, it has 4 single bonds, so the electron - domain geometry is tetrahedral. So Carbon 3 has Tetrahedral geometry.

Answer:

• Carbon 1: Tetrahedral (select the radio button under Tetrahedral for Carbon 1)
• Carbon 2: Trigonal Planar (select the radio button under Trigonal Planar for Carbon 2)
• Carbon 3: Tetrahedral (select the radio button under Tetrahedral for Carbon 3)
