Question :


How many $\sigma-$ bonds are present in tetra-isobutyl methane ? ​

Answer 1

Answer:

$\: \huge\sf\underline \red{\underline{αиѕωєя}}$

There are four single bonds present in methane as 4 hydrogen atom satisfies the carbon valency 4 which can be represented as shown in the figure.

Answer 2

Total no. of Sigma bonds present is tetra isobutyl methanr is 52.

Sigma Bond

• It is a type of covalent bond
• It is formed by axial overlapping
• In most cases, Sigma bond is the single bond between two atoms.
• there is one sigma and one pi bond in case of double bond
• There is one sigma and 2 pi bonds in case of triple bond.

Structure of Isobutyl methane $[ C_{4} H_{9} ]$

$CH_{3} - CH-CH_{2} \\ -CH_{3}$

• There are 9 single bonds of C and H and 3 single bonds are C-C bonds

• Isobutyl methane have 12 single bonds, that is 12 sigma bonds.

Tetra Isobutyl methane is formed by 4 Isobutyl methane attached to a central carbon

so, Sigma bonds = 4 x 12 + 4 (4 Isobutyl methane attached to C by 4 single bonds )

                            = 48 + 4

                            = 52

Hence, there are 52 sigma bonds present in tetra isobutyl methane.
