14.1 - Alkenes

Question 1

Reactivity of alkenes (bonds, density of the electrons and structural feature)

Answer 1

• contain double bond between carbon atoms - contribute to their high reactivity
• electron density of the C=C bond makes them highly accessible for reactions and allows alkenes to readily attract electrophiles
• structural feature of the double bond allows it to undergo reactions across the C=C bond

Question 2

Trigonal planar geometry of carbon in alkenes

Answer 2

in alkenes, each carbon atom within the C=C double bond has
3 regions of electron density
these regions are arranged in a trigonal planar shape due to equal repulsion between them
120 degrees approximately

Question 3

Key features of Alkenes

Answer 3

• consist of carbon and hydrogen atoms (hydrocarbons)
• each alkene molecule contains at least one carbon-carbon double bond
• makes them unsaturated

Question 4

General formula of Alkenes

Answer 4

have the general formula CnH2n
