Label each carbon atom with the appropriate geometry. Bin 1 points to a carbon bonded to a double bonded carbon and single bonded to two hydrogens. Bin 2 points to a carbon double bonded to a carbon and single bonded to a carbon and one hydrogen. Bin 3 is a carbon single bonded to two carbons and single bonded to two hydrogens. Bin 4 is the same as bin 3. Bin 5 is a carbon triple bonded to a carbon and single bonded to a carbon. Bin 6 is triple bonded to a carbon and single bonded to a hydrogen.

Bin 1 points to a carbon bonded to a double bonded carbon and single bonded to two hydrogens. --- trigonal planar, tetrahedral

Bin 2 points to a carbon double bonded to a carbon and single bonded to a carbon and one hydrogen. trigonal planar, tetrahedral

Bin 3 is a carbon single bonded to two carbons and single bonded to two hydrogens. tetrahedral, tetrahedral

Bin 4 is the same as bin 3.tetrahedral, tetrahedral

Bin 5 is a carbon triple bonded to a carbon and single bonded to a carbon. linear, tetrahedral

Bin 6 is triple bonded to a carbon and single bonded to a hydrogen.---linear, tetrahedral

Explanation:

A single C-C or C-H bond is in a tetrahedral geometry, the carbon atom is bonded to four species with a bond angle of 109°.

A C=C bond is trigonal planar with a bond angle of 120°.

Lastly, a C≡C bond has a linear geometry with a bond angle of 180° between the atoms of the bond.

i think   the answer is c hope i'm right

there are two significant figures.
