What is the approximate value of the ccc bond angle in
a. ch3ch2ch2oh
b. ch3c≡cch3
c. h2ccch2?

a)109° b)180° c)120°

Explanation:

Hi, in general the bond angle in any molecule depends of:

In particular for C atoms, there isn't free electron pairs so the angle only depends of the type of bond.

a) Propanol ( )

Is this molecule all C have single bonds and an hibridization of sp3, forming a tetrehedral geometry. The bond angle determined for this geometry is arround 109°

b)2-Butyne ( )

Is this molecule, the triple bond makes a sp hibridization, forming a linear geometry. The bond angle determined for this geometry is 180°

a) Propadiene ( )

Because of the double bonds, C have sp2 hibridization, forming a plain geometry. The bond angle determined for this geometry is 120°

answer; i believe the correct answer is (solid gold);

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
