Why does voltage leads or lags current by 90 degree in inductor and capacitor respectively, why not 85 degree for example?

If there is only one capacitor in an AC circuit, does the current shift 90 degrees regardless of the capacitance value?

On a chip, between GND and the pins, when I measure each pin individually in multimeter diode mode, if I see a value around 600-700mV, does this mean that the chip is undamaged?
