How to use in-sentence of “carbocation”:
– Gold Book definition In present-day chemistry, a carbocation is any positively charged carbon atom.
– A carbocation was previously often called a “carbonium ion” but chemists question the exact meaning.
– Additionally, bulky substituents on the central carbon increase the rate of carbocation formation because of the relief of steric strain that occurs.
– Since the S1 reaction involves formation of an unstable carbocation intermediate in the rate-determining step, anything that can help this will speed up the reaction.
– Finally, if the carbocation intermediate can rearrange to a more stable carbocation, it will give a product derived from the more stable carbocation rather than the simple substitution product.
– Therefore, reactions such as the SN1 reactionS1 reaction and the E1 elimination reaction normally do not occur if a primary carbocation would be formed.
– However, the chemical reactivityreactivity of a carbocation more closely resembles sp hybridization with a trigonal planar molecular geometry.
