.Which best describes the structure of 2-butene? A. a four-carbon hydrocarbon with a double bond between the second and third carbon atoms

B. a four-carbon hydrocarbon with a branching point at the second carbon atom in the chain

C. a four-carbon hydrocarbon with a double bond between the first and second carbon atoms​

A.

Explanation:

The 2 - butene is an alkene with the formula C4H8, which can be used as the polybutene monomer or co-polymer. It is a compressed liquefied gas colorless, highly flammable characteristic odor. Prolonged exposure to this gas can cause frostbite causing a lowering of consciousness. Its formula is C4H8 and it is made up of 4 carbon atoms.

The best structure that describes 2-butene is that of Option A.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
