Draw the kinetic and thermodynamic addition products formed when one equivalent of HBr reacts with the diene .

See explanation and images attached

Explanation:

The addition of HBr to the diene could yield either a kinetic or thermodynamic product. The kinetic product is formed faster while the thermodynamic product is more stable and formed at equilibrium.

Recall that the alkene that is surrounded by more alkyl groups is more stable. Also, the carbocation undergoes rearrangement to form a more stable carbocation intermediate that ultimately leads to the formation of the thermodynamic (1,4) product which predominates.

The structures of the two products are shown in the image attached to this answer.

The correct answer for above statement is:

both positive and negative .

Explanation:

DDT should be used "with caution" in fighting malaria,

DDT () was condemned in Britain in 1986 and prevented as a pesticide worldwide under the Stockholm Convention in 2001 after it was determined to be hazardous to wildlife and the environment.

The 15 environmental health specialists, who evaluated almost 500 health studies, decided that DDT "should be used with caution, only when needed, and when no other adequate, safe and affordable dilemmas are locally accessible.
