Which compound is an isomer of 2,2-dimethylpropane?

Structure (e) is named 2,2-dimethylpropane. There are only three structural isomers possible with the chemical formula C5H12: n-pentane, 2-methylbutane, and 2,2-dimethylpropane. Structural isomers have distinct physical and chemical properties.

Why is it called 2,2-dimethylpropane?

The second carbon atom is attached with two methyl groups as the parent chain contains three carbon atoms. Hence, the IUPAC name is $ 2,2 – {\text{dimethylpropane}} $ .

What is 2,2-dimethylpropane melting point?

2.48°F (-16.4°C)Neopentane / Melting point

Which of the following is the correct structure for 2/3 dimethyl pentane group of answer choices?

2,3-Dimethylpentane | C7H16 – PubChem.

How do you write the structural formula for 2,3-dimethylbutane?

How are pentane and 2-methylbutane related?

Count the number of carbon atoms in total in a molecule of 2-methylbutane (5), and the total number of hydrogen atoms (12), so the molecular formula of 2-methylbutane is the same as that for pentane, that is, C5H12, therefore pentane and 2-methylbutane are structural isomers.

How many structural isomers are possible for pentane?

three structural isomers
Pentane (C5H12) is an organic compound with five carbon atoms. Pentane has three structural isomers that are n-pentane, Iso-pentane (methyl butane) and neopentane (dimethylpropane). Therefore three structural isomers can be drawn from pentane.

Which molecule has higher boiling point pentane or 2,2-dimethylpropane?

The boiling point of pentane is 36∘ and that of 2,2-dimethylpropane is 9∘. Therefore, the boiling point of pentane is higher than 2,2-dimethylpropane. As the molecular mass increases, Van der Waals force increases. Hence the boiling point increases steadily with increase in molecular mass.
