Question

33. Co4 (CO) 12 adopts the
(a) closo-structure
(c) arachno-structure
(b) nido-structure
(d) hypho-structure​

Answer 1

$\huge \bf \pink{ANSWER}$

Co4 (CO) 12 adopts the?

→Closo-structure.

Answer 2

Answer:

An accurate answer is an option (a) →Closo-structure.

Explanation:

Closo borane is one of the three major formation of borane which has the chemical formula $B_{n}H_{n}^{2-}$. The boron atoms of these formation are in the corners of a polyhedron. employs characteristic structural prefixes:

(1) closo- (a corruption of “clovo,” from Latin clovis, meaning “cage”), Deltahedron of n boron atoms;

(2) nido- (from Latin nidus, meaning “nest”), nonclosed formation in which the $B_{n}$ cluster tenanted $n$ corners of an ($n + 1$)-cornered polyhedron.

Hence, the correct answer is option (a) →Closo-structure.
