Question

no of sigma and π bond in hexan-2,4-dione​

Answer 1

Answer:

3....,............................

Answer 2

Explanation:-

First let us draw the structure of

hexan-2,4-di one

steps to draw:-

↔Hexan indicates that there are 6

carbons with all single bonds

↔At 2nd and 4th position we have

ketone functional group (=O)

↔keeping in mind that valency of

carbon is 4 fill the remaining hydrogens

Number of sigma bonds:-

Number of C-H bonds+number of

oxygen bonds+number of C-C

bonds=10+2+5=17

$\boxed{\sf no.\: of \: sigma\: bonds =17}$

Number of pi bonds:-

Number of oxygen bonds=2

$\boxed{\sf no.\: of \: pi\: bonds =2}$

Note:-

↔=O gives 1 pi bond and 1 sigma bond
