Question

Which of the following conversions involves change in both shape and hybridisation ? (A) NH 3 arrow NH 4+ (B) CH 4 arrow C 2 H 6 (C) H 2 O arrow H 3 O + (D) BF 3 arrow BF 4-

Tardigrade Admin · Accepted Answer

BF 3 combines with F - ion to form BF 4-. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/0614bb46c19d29c9891573b394388c99-.png" /> The shape of the BF 3 molecule is a planar triangle with bond angles of 120° and s p2 hybridisation. The shape of the BF 4-1 molecule is a tetrahedral with bond angles of 108° and s p3 hybridisation.

Q. Which of the following conversions involves change in both shape and hybridisation ?

$N H_{3} \to N H_{4}^{+}$

$C H_{4} \to C_{2} H_{6}$

$H_{2} O \to H_{3} O^{+}$

Q. Which of the following conversions involves change in both shape and hybridisation ?

NH3​→NH4+​

CH4​→C2​H6​

H2​O→H3​O+

BF3​→BF4−​

BF3​ combines with F− ion to form BF4−​. The shape of the BF3​ molecule is a planar triangle with bond angles of 120∘ and sp2 hybridisation. The shape of the BF4−1​ molecule is a tetrahedral with bond angles of 108∘ and sp3 hybridisation.

$N H_{3} \to N H_{4}^{+}$

$C H_{4} \to C_{2} H_{6}$

$H_{2} O \to H_{3} O^{+}$

$B F_{3} \to B F_{4}^{-}$
