Consider the following mechanism for the formation of tert-butanol: (CH_3)_3CBr(aq) rightarrow (Ch_3)_3 C^+ (aq) + Br^- (aq) (CH
Sloan [31]

Answer:

The mechanism is in the attached file. The reaction intermediates are the following: C4H8O, C4H9O

Explanation:

Terbutanol is a tertiary alcohol. It is one of the four isomers of butanol. It is a transparent liquid (or a colorless solid, depending on the temperature), with an odor similar to camphor. It is very soluble in water and ethanol.

The scheme shows a protonation of the double bond and the nucleophilic attack of the water to the carbocation, then it loses a proton and the terbutanol is formed.

Lead has a density of 11.3 g/cm3 . what is the volume of a 15.1 g block of lead?
natita [175]
Hey there:

density = 11.3 g/cm³

mass = 15,1 g

Therefore: 

D = m / V

11.3 = 15.1 / V

V = 15.1 / 11.3

V = 1.336 cm³
