Double bonds drawing

Commonly used in biology as a tissue preservative, formaldehyde, CIDO, contains a carbon -oxygen double bond. Draw the line-bond structure of formaldehyde, and indicate the hybridization of the carbon atom. 

Allerie, P12C — C = CH2> is somewhat unusual in that it has two adjacent double bonds. Draw a picture showing the orbitals involved in the u and -n- bonds of allene. Is the central carbon atom sp2- or sp-hybridized What about the hybridization of the terminal carbons What shape do you predict for allene ... 

A anmileue is a compound with three adjacent double bonds. Draw an orbital picture of a cumulene. What kind of hybridization do the two central carbon atoms have What is the geometric relationship of the substituents on one end to the substituents on the other end What kind of isomerism is possible Make a model to help see the answer. 

When you do the same reaction (as above) in the presence of peroxides (R-O-O-R), you get an anti-Markovnikov addition of HBr across the double bond. Draw the product of an anti-Markovnikov addition. 

Which of the structures shown in both exercises 55 and 56 are 2-methyl-2-pentene, where 2 indicates the placement of the double bond Draw a box around them. 

Formaldehyde, CH 0, contains a carbon-oj ge/i double bond. Draw Lewis and line-bond structunes of Ibmialdehyde. and indicate the bybridizatiou of the carbon atom. 

Given that syn addition of H2 occurs from both sides of a trigonal planar double bond, draw all stereoisomers formed when each alkene is treated with H2. 

PROBLEM 14.9 Gutta-percha, a less common form of natural rubber, is also a 1,4-polymer of isoprene, but with E double bonds. Draw the structural formula for a three-monomer segment of gutta-percha. 

When drawing double bonds, draw all bonds as far apart as possible ... 

Linoleic acid is a 18-carbon unsaturated fatty acid with two double bonds. Draw the condensed structural formula for glyceryl trilinoleate (trilinolein).
