1. From pentane to octane the alkanes are highly volatile liquids. 2. Syn-pentane strain is an example of this situation. 3. The parent five-carbon compound is named pentane ( highlighted blue ). 4. It is the substituent form of the alkane pentane . 5. 1, 3-diaxial strain is another form of strain similar to syn-pentane . 6. Allylic strain, or A 1, 3 strain is closely associated to syn-pentane strain. 7. The hydrolysis of dichlorosilane in diethyl ether, dichloromethane, or pentane gives cyclic and linear polysiloxanes. 8. After stirring 4 hours at room temperature the solution was diluted with brine and extracted with pentane . 9. Carbon monoxide dissolved in pentane reacted with a uranium coordination compound yielding a deltate anion bound to two uranium atoms. 10. The branched isomers are more stable ( have lower heat of formation and heat of combustion ) than n-pentane .
