What product is formed when 1-bromopropane reacts with ch3o−?
STatiana [176]
When 1-Bromopropane is treated with methoxide it undergoes SN² Reaction. The product formed is Methyl Propyl Ether. This type of reaction is very important in synthesizing Asymmetric ethers. The alkoxides are oftenly generated by reacting Alcohols with sodium metal, which on elimination of Hydrogen gas produces corresponding alkoxide. The reaction of given statement is as follow,

Answer:

The density is  \rho =  8.21479 g/cm^3

Explanation:

From the question we are told that

         the lattice constant is  a =  0.295 nm = 0.295*10^{-9} = 0.295*10^{-7} cm

The density of Copper (\beta) is mathematically represented as

     \rho  =  \frac{ZM}{a^3N_A}

Where  Z is the number of units in a unit cell and  for BCC crystals  Z =2

          M is the molar mass of copper which same for Copper with a value of  

           M =  63.5  g/mol

          N_A is the Avogadro's constant with a value of  N_A =  6.022*10^{23}

Substituting values

       \rho =  \frac{2 *63.5}{(0.295*10^{-7})^3 * (6.022*10^{23})}

      \rho =  8.21479 g/cm^3
