Question

Identify the following compounds as a(n) alkane, alkene, alkyne, cycloalkane, or cycloalkene: 2. Family Molecule Family Molecule ннННн T I T I Н-С-С-С-С-С-Н CH3-CH2. нНН Н H-C-H CH3 Н CH На. CH CH-CH CH3 CH2-CH2-CH=C-CH3 НС CH3-CH-C CH CHs-CH-CH-CH3 CH2-CH CH2-CH2

Answer 1

We can classify the given compounds as follows whether they contain any double bond, triple bond,or cyclic ring etc.

Molecule Family Molecule H H H H H-C-C-( (-(-H Allan CH₃ CH2 Cycloalkene HHHH H- (-H (H₂ н Cl₂ Alkane CH-CH CH₃ (H=C-CH₂ Alkene CH3 -Cth СН3 CH2-(4- CH₂ - CH3 Cycloalkane CH3 -(41-CECH CH₂ - CH2 Alkyne CH2 CH₂

this is an example for alkane, since it doesn't contain any double bond or triple bond.

н нннн y-t-t-(-C-C-H Aikine н н н Н и – С – Н

This is an example for alkene, since it contains a double bond.

Cth CH3 -CH2 – CH=C-CHE Alkene

This is an example for cycloalkanes, since it contains a four membered cycle.

CH₂ - (14-CH₂ - CH3 Cycloalkane CH₂ - CH2

This is an example for cycloalkene, since it contains a four membered cyclic group which contains a double bond.

CH₃CH2 C on Cyclcalkede cycloalkene CH₃

This is an example for alkane , since it doesn't contain any double bond or triple bond or cyclic group.

CH₃ CH-CH Alkane CH3 CH₂

This is an example for alkyne, since it contains a triple bond in its chain.

CH₃-CH-CECH Alkyne СН2-СН3
