Answer:

The correct answer is 4 substracting hydride ions from olefins.

Explanation:

The olefins are the unsaturated hydrocarbon also called alkenes that contain one double bond present between 2 carbon atoms.

   On the other hand a carbenium ion is formed when a hydrocarbon loses a hydride ion to form a positively charged product.

  For example allyl cation

               CH2=CH-CH2+

The allyl cation is a carbenium ion formed by the removal of H- ion or hydride ion from the alkene propene.

A gas at 200 K occupies a volume of 350 ml. What temperature is needed to increase the volume
Rudik [331]

Answer: Temperature in constant pressure is 286 K

Explanation: If pressure remains constant, then V/T = constant.

V1 = 350 ml and T1 = 200 K and V2 = 500 ml.  V1/T1 = V2/T2

and T2 = T1· V2 / V1 = 200 K · 500 ml / 300 ml = 285,7 K
