Question

Which one of the molecules shown below has net molecular dipole moment A) CH B) HC-CH c) Co D) CCl S. Which of the molecules below can hydrogen bond to another of the same compound? A) CH,CH,OCH CH, B) CH CH COOCH D) (CH CH2) CHOH E) all of the above 9. Which of the functional groups below contains a hydroxyl group as a part of their structure? A) alcohol B) aldehyde C) ether D) amine E) Band C only Which of the following structure is invalid bused on your understanding of the number of valence bonds for atoms? 10. What is the hybridization of the nitrogen atom in the molecule below? 11. A) sp B) sp D) sp'd E) sp'd

Explanation / Answer

7. answer is E. CH3OH. Here central metal atom is C and other parts are arranged in tetrahedral passion. Since, OH is present, this molecule have net dipole moment.

8. D since the compound contains -OH group, we will observe the hydrogen bonding with same molecule.

9. A alcohol contains -OH. aldehyde -CHO, ether -C-O-C-, amine -NH2.

10. B, the compound carbon has five bonds (two with oxygen, two with hydrogen, one with carbon). The bonds allowed for the carbon is only four.

11. the nitrogen is having one lone pair and three bond pairs. So, this will have sp3.
