Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.

Question

Why do alkanes, alkenes, and alkynes have a relatively low boiling point? (Select all answers)

They have a lot of electron density in a very small amount of space.

They have no large intermolecular forces holding them together.

They have no dipole moments or polarity.

Definition Definition Simplest organic compounds that contain only single bonds between carbon – carbon atoms and carbon – hydrogen bonds. This means they are a series of saturated compounds with a general molecular formula, C n H 2n+2 .

What is the name of the IUPAC compound shown here? (see attatchement) First time you guys answered it was wrong, trying again. **** The answer 3-methylbut-1-ene you gave yesterday was WRONG . Please help with correct answer. This is what the question has as well: Alkanes are called saturated hydrocarbons because each carbon atom has the maximum number of hydrogen atoms. In contrast, alkenes and alkynes are unsaturated because they contain double or triple bonds that reduce the number of hydrogen atoms in the compound. When naming unsaturated hydrocarbons, a suffix reflects the type of multiple bond in the compound: ene is used for alkenes (double bond), and yne is used for alkynes (triple bond). For cyclic alkenes and alkynes, the ring is numbered such that the double or triple bond is between the first two carbon atoms. For straight-chain molecules, the numbering starts at one end of the chain, so the location of the double or triple bond must be specified in the name.

Based on your knowledge of boiling point trends in alkanes, predict which compound has the higher boiling point, butane or 2-methylpropane (isobutane). Based on your knowledge of boiling point trends in alkanes, predict which compound has the higher boiling point, butane or 2-methylpropane (isobutane). a. isobutane would have a higher boiling point, since the greater the surface area, the higher the boiling point. b. Butane would have a higher boiling point, since the greater the surface area, the higher the boiling point. c. Butane would have a higher boiling point, since the smaller the surface area, the higher the boiling point. d. Isobutane would have a higher boiling point, since the smaller the surface area, the higher the boiling point.
