of its chemical reactions occur

Answer 2

Functional group

Question 3

are the functional group for an unsaturated hydrocarbon.

Answer 3

Carbon–carbon multiple bonds

Question 4

Is an acyclic unsaturated hydrocarbon that contains one or more carbon–carbon double bonds.

Answer 4

ALKENES

Question 5

is a cyclic unsaturated hydrocarbon that contains one or more carbon– carbon double bonds within the ring system.

Answer 5

Cycloalkenes

Question 6

The simplest cycloalkene is the compound _______ , a three membered carbon ring system containing one double bond.

Answer 6

cyclopropene (C₃H₄),

Question 7

is an acyclic unsaturated hydrocarbon that contains one or more carbon–carbon triple bonds.

Answer 7

ALKYNES

Question 8

These are constitutional isomers with the same carbon-chain
arrangement but different hydrogen atom arrangements as the result of differing location of the functional group present

Answer 8

Positional isomers

Question 9

_______ are constitutional isomers that have different carbon-chain arrangements as well as different hydrogen atom arrangements

Answer 9

Skeletal isomers

Question 10

An ____________ is a reaction in which atoms or
groups of atoms are added to each carbon atom of a carbon–carbon multiple bond in a hydrocarbon or hydrocarbon derivative

Answer 10

addition reaction

Question 11

A ____________ is
an addition reaction in which identical atoms (or groups of atoms) are added to each carbon of a carbon–carbon multiple bond.

Answer 11

symmetrical addition reaction

Question 12

An ___________ is an addition reaction in which
different atoms (or groups of atoms) are added to the carbon atoms of a carbon–carbon multiple bond.

Answer 12

unsymmetrical addition reaction

Question 13

A _________ is an addition reaction in which H2 is
incorporated into molecules of an organic compound.

Answer 13

hydrogenation reaction

Question 14

A __________ is an addition
reaction in which a halogen is
incorporated into molecules of an
organic compound.

Answer 14

Halogenation
Reaction

Question 15

A _____________ is an addition reaction in which a
hydrogen halide (HCl, HBr, or HI) is incorporated into molecules of an organic compound.

Answer 15

hydrohalogenation reaction

Question 16

A ___________ is an addition reaction in which H2O is
incorporated into molecules of an organic compound.

Answer 16

hydration reaction

Question 17

When two isomeric products are possible, one product usually predominates. The dominant product can be predicted by using Markovnikov’s rule.

Answer 17

Reactions of Alkenes

Question 18

This rule states that when an unsymmetrical molecule of the form HQ adds to an unsymmetrical alkene, the hydrogen atom from the HQ becomes attached to the unsaturated carbon atom that already has the most hydrogen atoms.

Answer 18

Markovnikov’s rule

Question 19

The same substances that add to double
bonds (H2, HCl, Cl2, and so on) also add to
triple bonds.
