Draw the alkyne formed when 2,3-dichloropentane is treated with an excess of strong base such as sodium amide.

We obtain the alkyne 2-pentyne through E2 reaction mechanism.

Explanation:

Alkyl halides are compounds that contain a carbon chain in which one or more hydrogen atoms have been replaced by a halogen atom (F, Cl, Br, I) and are characterized by having halogen atoms in adjacent carbons. In the dehydrohalogenation the alkyl halide is reacted with a strong base. As a result an alkyne is obtained.

In this case we use sodium amide to favor the type E2 reaction mechanism (type 2 elimination) and we obtain the following alkyne:

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
