Question

How many of the following trends is(are) CORRECT with respect to properties of hydrides of group 16 elements? i. Bond angle: H 2 O > H 2 S > H 2 Se > H 2 Te ii. Volatility: H 2 O < H 2 S > H 2 Se > H 2 Te iii. Thermal stability: H 2 O > H 2 S > H 2 Se > H 2 Te iv. Acidic strength: H 2 O > H 2 S > H 2 Se > H 2 Te (A)  (B)  (C)  (D)

(i), (ii) and (iii) are correct. Acidic strength of the hydrides of group 16 follows the trend: H 2 O < H 2 S < H 2 Se < H 2 Te

(i),(ii) and (iii) are correct. Acidic strength of the hydrides of group 16 follows the trend: H2​O<H2​S<H2​Se<H2​Te

$(i), (ii)$ and $(iii)$ are correct. Acidic strength of the hydrides of group $16$ follows the trend: $H_{2} O < H_{2} S < H_{2} S e < H_{2} T e$
