What properties would you expect to be different for the two enantiomers of 2-pentanol?

direction of rotation of plane polarized light and reaction with chiral reagents.

Explanation:

Enantiomers are stereoisimers which are mirror images of each other. They possess the same physical and chemical properties except that the direction of rotation of plane polarized light and reaction with chiral reagents. (+)-2-pentanol will rotate plane polarized light to the right and react with dextrorotatory enantiomers of chiral reagents while (-)-2-pentanol will rotate plane polarized light to the left and react with leavorotatory enantiomers of chiral reagents.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
