Q17 / 160 · TS EAMCET 2020 (11 Sep Shift 2) · Chemistry

Buckminister fullerene contains the following $X$ number of six and $Y$ number of five member rings. What is the value of $X$ and $Y$ ?

  • A
    $X=10, Y=12$
  • B
    $X=15, Y=15$
  • Correct answer
    C
    $X=20, Y=12$
  • D
    $X=10, Y=20$

Solution

Buckminister fullerene is a type of fullerene with formula $\mathrm{C}_{60}$. It has a cage like fused sings that resembles a soccer ball. Buckminister fullerene contain even number of carbon atoms with 12-(twelve) five membered rings and 20 six membered rings, i.e. $(X)=20 \Rightarrow(Y)=12$

Hence, the correct answer is option: 'C'.
