Chapter 12, Problem 44PP

(a)

Interpretation Introduction

Interpretation: To find the product and mechanism of the reactions by lithium aluminum hydride.

Concept introduction:

Hydride reacts with the carbonyl group, C=O of aldehydes or ketones to give alcohols.

  LiAlH4 is a reducing agent which can reduce up to alcohol only. It can't reduce any compounds to alkanes. It is more reactive than sodium borohydride.

(b)

Interpretation Introduction

Interpretation: To find the product and mechanism of the reactions by sodium borohydride.

Concept introduction:

Hydride reacts with the carbonyl group, C=O , of aldehydes or ketones to give alcohols.

Sodium borohydride is comparatively less reactive in comparison to lithium aluminum hydride. It easily reduces aldehydes and ketones and converts them into alcohols effectively. Acids, nitriles, esters, and amides are mostly unaffected. When interacting with halides and epoxides, it can also act as a nucleophile.

30. We will derive the forms of the molecular partition functions for atoms and molecules shortly in class, but the partition function that describes the translational and rotational motion of a homonuclear diatomic molecule is given by Itrans (V,T) = = 2πmkBT h² V grot (T) 4π²IKBT h² Where h is Planck's constant and I is molecular moment of inertia. The overall partition function is qmolec Qtrans qrot. Find the energy, enthalpy, entropy, and Helmholtz free energy for the translational and rotational modes of 1 mole of oxygen molecules and 1 mole of iodine molecules at 50 K and at 300 K and with a volume of 1 m³. Here is some useful data: Moment of inertia: I2 I 7.46 x 10- 45 kg m² 2 O2 I 1.91 x 101 -46 kg m²
