Problem 93AE

Problem 93AE

The lactic acid molecule, CH3CH(OH)COOH, gives sour milk its unpleasant, sour taste. (a) Draw the Lewis structure for the molecule, assuming that carbon always forms four bonds in its stable compounds., (b) How many π and how many s bonds are in the molecule? (c) Which CO bond is shortest in the molecule? (d) What is the hybridization of atomic orbitals around the carbon atom associated with that short bond? (e) What are the approximate bond angles around each carbon atom in the molecule?

Step-by-Step Solution:
Step 1 of 3

Problem 93AEThe lactic acid molecule, CH CH(OH)CO3, gives sour milk its unpleasant, sour taste. (a)Draw the Lewis structure for the molecule, assuming that carbon always forms four bondsin its stable compounds., (b) How many and how many s bonds are in the molecule (c)Which CO bond is shortest in the molecule (d) What is the hybridization of atomicorbitals around the carbon atom associated with that short bond (e) What are theapproximate bond angles around each carbon atom in the moleculeSolution 93AEStep-1(a) Here we have to draw the Lewis structure for lactic acid molecule (CH CH(OH)COOH), 3assuming that carbon always forms four bonds in its stable compounds.In order to draw the Lewis dot structure, 1st we have to calculate the total number of valenceelectron present in the molecule. 2 2 2 2 2 4 16 1s 2s 2p 8 1s 2s 2p 1 1sThe total number of valence electron = 3 (4) + 6 (1) + 3 (6) = 36 electronsThe Lewis dot structure is given below,Step-2 (b) Here we have to find out how many and how many s bonds are in the molecule.The above molecule contain 11 sigma ( ) bonds and 1 pi () bond.\nStep-3 (c) Here we have to find out which CO bond is shortest in the moleculeIt is known that greater the bond order shorter the bond length. The C=O bond present on theright hand C atom is shortest bond due its greatest bond order.Step-4(d) Here we have to find out the hybridization of atomic orbitals around the carbon atomassociated with that short bond.The C-atom which has short bond is C=O, present on the right hand side. This C atom issurrounded by three electron domain. That means it can form three hybrid orbital i.e sp 2hybridization. Both the C-atoms which are present at the middle and left-hand side aresurrounded by four electron domains, hence can form four hybrid orbitals i.e sp hybridization.Step-5 (e) Here we have to find out the approximate bond angles around each carbon atom in themolecule.The C-atom which is sp hybridized has bond angle 120 and the C-atoms which are sp 3hybridized have bond angle 109 . o
