Draw the skeletal (line-angle) structure for 2,4-dibromo-2-methylheptane. Enter each of your answers as integers. How many total carbons are in the structure? How many primary carbons are in the structure? How many secondary carbons are in the structure? How many tertiary carbons are in the structure? How many quaternary carbons are in the structure?

Explanation:

       Br           Br

c-      c     -c    -c    -c    -c     -c

       Ch3

Bromine on the 2nd and 4th C   methyl on the 2nd carbon  

8 total carbons     7 primary   1 tertiary  the 2nd carbon is attached to 3 others

no quaternary  none bonded to 4 others

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
