Explanation
- sp³d² hybridization occurs in octahedral geometry.
- K₃[CoF₆] has Co³⁺ (d⁶ configuration) in a high-spin state, leading to sp³d² hybridization.
Explanation
- The rate law depends on the slowest (rate-determining) step, which is 2NO₂ → NO₃ + NO.
- Since this step involves two NO₂ molecules, the rate law is Rate = K₁[NO₂]²
الکلائن میڈیم میں فینولفتھیلین کا گلابی رنگ ______ ہے؟
Explanation
Phenolphthalein is colorless in acidic and neutral solutions but turns pink in an alkaline medium.
This happens because, in a basic solution, phenolphthalein loses H⁺ ions, forming its negatively charged phenolate ion, which gives the pink color.
Explanation
- Lions roar, while bears growl.
- Cats meow, Cows moo, and Elephants trumpet.
Explanation
- In voltammetry, the potential difference (voltage) is controlled and varied while measuring the resulting current.
- This technique helps analyze redox reactions and detect specific ions or compounds in a solution.
Explanation
- Methane (CH₄) is the simplest hydrocarbon.
- It is consisting of one carbon atom bonded to four hydrogen atoms.
- It is the primary component of natural gas.
- It is widely used as a fuel source.

Explanation
- Lucas reagent is a mixture of concentrated hydrochloric acid (HCl) and anhydrous zinc chloride (ZnCl₂).
- It is used to differentiate primary, secondary, and tertiary alcohols based on their reaction rates.
Explanation
- Elements that form XF₄ compounds typically belong to Group 14 (like Sn, Si, Ge), which can form stable tetrahalides (XF₄).
- Sc (Scandium) belongs to Group 3 and does not form XF₄ type compounds.
