What is the name of the product of the reaction of 1-pentyne with one equivalent of Br2? (that means that there is one mole of Br2 for each mole of 1-pentyne).

The name of the product of the reaction of:

1-pentyne with one equivalent of Br2, that means that there is one mole of Br2 for each mole of 1-pentyne, is:

Dihalogenated alkane

Explanation:

When 1-pentyne reacts with one molar equivalent of diatomic bromine the product is dibromide, a dihalogenated alkane. This alkene halogenation reaction mechanism for the bromination of alkene, occurs when dihalide such as Br2 is added to a molecule after breaking the carbon to carbon double bond.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

there is none because earth is stationary and flat.
