NH₃ आणि BF₃ च्या आकारांबद्दल खालीलपैकी कोणता पर्याय अचूक आहे ? Which of the following is correct for the shapes of NH₃ and BF₃ ?
a)NH₃ - पिरॅमिडल आणि BF₃ - पिरॅमिडल / NH₃ - Pyramidal and BF₃ - Pyramidal
b)NH₃ - प्लेनर आणि BF₃ - प्लेनर / NH₃ - Planar and BF₃ - Planar
c)NH₃ - प्लेनर आणि BF₃ - पिरॅमिडल / NH₃ - Planar and BF₃ - Pyramidal
d)NH₃ - पिरॅमिडल आणि BF₃ - प्लेनर / NH₃ - Pyramidal and BF₃ - Planar✓ Correct
NH3 has 3 bond pairs and 1 lone pair, resulting in a pyramidal shape due to sp3 hybridization and lone pair-bond pair repulsion. BF3 has 3 bond pairs and no lone pairs, resulting in a trigonal planar shape due to sp2 hybridization.
