Question

cumulated dienes two examples​

Answer 1

Answer:

The simplest cumulated diene is 1,2-propadiene, CH2=C=CH2, also known as allene. Indeed, cumulated dienes are often called allenes. The central carbon in such compounds is sp-hybridized (it has only two bonding partners), and the double bond array is linear as a result.

Answer 2

Answer:

Examples of cumulated dienes are 1,2 Butadiene and 4,5 Pentadiene.

Explanation:

• A molecule called diene has two double bonds between its carbon atoms and is unsaturated.
• Diene is employed in industry as a complex polymer's monomer constituent.
• Two sequential double bonds are present on nearby Carbons in a cumulated diene.
• They go by the name Allene too.
• The double bond's immediate neighbouring location in a diene is acidic. Diene's acidic nature results from the allyl ion's increased stability brought on by resonance.
• Due to the delocalization of electron clouds on Carbon atoms, conjugated dienes are more stable than non-conjugated dienes.
• Dienes are frequently employed in industry as the basic building blocks of sophisticated polymers.
• When butadiene polymerizes, buna rubber—used in tyres—is created.
• As isoprene polymerizes, natural rubber is created.
• Dienes are also employed to create organic compounds.

1,2 Butadiene and 4,5 Pentadiene are examples of cumulated dienes.
