• First you have to know what ‘cumulene’ looks like,

  H2C=C=C=CH2

  Hopefully that picture makes sense otherwise you can just search it in Google and you can get a picture.

  The outside two carbons are sp2 hybridized while the inner carbons are sp hybridized.

  Sigma bonds are anytime you have a single bond between molecules and a double bond is made up of a sigma bond and a pi bond. The sigma bonds are made up of overlap of two of the hybridized orbitals, while the pi bonds are caused by the overlap of two p orbitals.

  A: 3 sigma bonds, and 3 pi bonds

  The two middle carbons both have sp hybridization so that bond is sp sp.

  The outside carbons are sp2 bonding with the sp of the middle carbons.

  So these apply,

  A. sp/sp overlap

  C. p/p overlap

  F. sp/sp^2 overlap

  Hopefully that helps!

• A pi bond is a bond. A sigma bond is a bond. A sigma bond and a pi bond make a double bond – 2 bonds. you may nicely be perplexed by ability of the undeniable fact that a pi bond is formed from 2 volumes of electron density – above and decrease than the bonded nuclei. jointly they form a pi bond. Our language fails us! a pair of pants is one merchandise of clothing, a double bond is two bonds. we would desire to continuously quite say “a pair of pant” and “a double bonds. yet, unluckily, we don’t.

• In cumulene, what are the C=C=C and H−C−H bond angles, respectively?

• o00hhhlalaa is correct on my chem lab answers

• The degrees are (180,119)

  (How many atoms / 360) = the bond angle

• 7sigma, 3pi

• the correct answer for the first question is 7,3 and for the second

  sp/sp

  sp/sp2

  s/sp2

  p/p

• THE ANSWER IS 7,3 NOT NOT NOT 3,3 WHY THE HELL IS THAT CLICKED AS BEST ANSWER….
