A. The functions f(x) and g(x) be derivable in (a, b)
B. None of these
C. The derivation of g(x) be equal to 0
D. The functions, f(x) and g(x) be continous in [a,b]
Explanation
Cauchy's Mean Value Theorem states that if two functions f(x) and g(x) are continuous on the closed interval [a, b] and differentiable on the open interval (a, b), and g'(x) ≠ 0 for any x in (a, b), then there exists a point c in (a, b) such that: (f'(c) / g'(c)) = (f(b) - f(a)) / (g(b) - g(a))
The necessary conditions for Cauchy's Mean Value Theorem are :
1. The functions f(x) and g(x) are continuous on [a, b]. 2. The functions f(x) and g(x) are differentiable on (a, b). 3. g'(x) ≠ 0 for any x in (a, b).

کسی بھی کیمیائی تبدیلی کے لئے توازن مستقل کی عددی قدر ______ کو تبدیل کرنے سے متاثر ہوتی ہے؟
A. Concentration of the products
B. None of these
C. Concentration of reacting substances

A. Secondary
B. None of these
C. Tertiary
D. Primary
Explanation
SN² reactions prefer primary and secondary alkyl halides due to less steric hindrance. Tertiary alkyl halides do not undergo SN² reactions because of high steric hindrance , making backside attack difficult.

A. Mean; Standard deviation
B. Accuracy; Standard deviation
C. Mean; Accuracy
D. None of these
Explanation
Gaussian distribution (normal distribution) is defined by its mean (central value). Standard deviation measures the spread of data around the mean.

رد عمل کا انفالپی ایک ہی ہے چاہے رد عمل ایک یا کئی مراحل میں ہوتا ہے۔ یہ کے طور پر جانا جاتا ہے؟
A. None of these
B. Hess's law
C. Boyle's law
