Question

Which of the following shapes best describes the shape of the CO_2 molecule? linear bent tetrahedral trigonal planar What type of hybridization is involved in the carbon of carbonic acid, H_2CO_3? sp sp^2 sp^3 sp^3d^2 A double bond between a Carbon atom and an Oxygen atom consists of 2 sigma-bonds 2 pi-bonds 1 sigma-bond and 1 pi-bond 1 sigma-bond and 2 pi-bonds What is the molecular shape of ammonia (NH_3)? bent trigonal pyramidal trigonal planar tetrahedral What is the molecular shape of the ammonium on (NH_4^+) bent trigonal pyramidal trigonal planar tetrahedral The bond angles marked a, b. and c in the molecule below would respectively be closest to a = 90 degree. b = 90 degree, c = 90 degree a = 120 degree, b = 120 degree. c = 90 degree a= 120 degree, . b= 120 degree. c = 109.5 degree d a = 109 5#. b = 120 degree. c = 109 5 degree In the molecule in #6 the N-C bond (beteen atoms a and b) results from the overlap of a orbital from the N atom and a orbital from the C atom sp^2, sp^2 sp^2. sp^3 sp^3, sp^2 sp^3, sp^3 sp^3. p_z

Explanation / Answer

1.

a. Linear

C in CO2 molecule is in SP hybridization

Sp hybridization means two hybrid orbitals

2.

option B is correct

H2CO3

here C is in SP2 hybridization

two hybrid orbitals are around one center shape shoul d be linear

3.

option C is correct answer

1 sigma and 1 Pi bond is correct answer.

4.

option B is correct answer

shape is trigonal pyramidal
